To reduce battery use from your iPhone’s dimmed Lock Screen, go to Settings > Display & Brightness > Always On Display. Turn off Always On Display to stop the screen staying visible while the phone is locked, or keep it on and switch off Show Wallpaper and/or Show Notifications to retain a simpler at-a-glance display. Apple does not publish a specific battery-savings percentage for these changes.
Choose how much of the Lock Screen to keep visible
On supported iPhone models, Always-On Display keeps a dimmed version of the Lock Screen visible while the phone is locked. Apple provides three controls in the same settings menu, so you can choose between disabling the feature and simplifying what it shows.

When Always-On Display switches off automatically
You may not need to change the setting for the display to go dark in every situation. Apple says Always-On Display turns off automatically when the iPhone is face down or obstructed from view, is not near a paired Apple Watch, starts a CarPlay session, or is using Continuity Camera. It also switches off when Low Power Mode or Sleep Focus is on, and at the user’s usual bedtime. These automatic conditions are separate from the Always On Display switch in Settings.

Use Low Power Mode to switch it off automatically
Low Power Mode disables Always-On Display as part of its broader effort to reduce power use. The Settings route depends on the iPhone generation:
- iPhone 15 and later: Settings > Battery > Power Mode > Low Power Mode.
- iPhone 14 and earlier: Settings > Battery > Low Power Mode.
Low Power Mode also reduces or disables other features to save power. It automatically turns off once the iPhone charges to 80% or higher. Apple lists the paths and behavior in its Low Power Mode support guide.

Adaptive Power is a separate option on compatible iPhones
Adaptive Power is not the Always-On Display setting. On supported iPhones, it can make adjustments intended to extend battery life, including slightly lowering screen brightness, limiting background activity, and adjusting performance. It can also turn on Low Power Mode when the battery reaches 20%.

What to expect from the battery change
Turning off Always-On Display removes its persistent dimmed Lock Screen, while hiding wallpaper or notifications lets you keep the feature with less visible content. Apple’s cited support pages do not quantify how much battery any of these choices saves, so there is no supported percentage or number of extra hours to promise.
Always-On Display is available only on supported iPhone models. Apple’s cited guide does not enumerate every compatible model; if you do not see the setting, the feature may not be available on your iPhone. These settings require no accessory.
